6' PASSENGER-CAR COOLER AND VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 483,710, dated October4, 1892.

Application filed April 8, 1892. Serial No. 428,277- (No model.) i

.To all whom it may concern:

Be it known that I, ALEXANDER BLAoK, a citizen of the UnitedStates,residing at Toledo, in the county of Lucas and State of Ohio,have invented certain new and useful Improvements in Passenger-CarCoolers and Ventilators; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in passenger-car coolers andventilators of the variety in which mechanism is provided to be used inconjunction with the ordinary carwindow; and the objects ofmyimprovements are, first, to provide means for conducting air morefreely from the outside atmosphere to the interior of the car; second,to provide means to regulate the quantity of the inflow, and,third, itsquality. I attain these objects by the mechanism illustrated in theaccompanying drawings, in Which Figure 1 is a perspective viewof theentire mechanism, showing prominently the side which is located withinthe car. Fig. 2 is a perspective View of the mechanism, showing the sidewhich is located without the car. Fig. 3 is a perspective view of themechanism like that shown in Fig. 1, but having its screensash adjustedin a different position. Fig. 4 is a perspective View of the apparatuslocated within a car-window and showing the said apparatus as it appearswithin the interior of the car and in operating position.

Similar letters refer to si milar parts throughout the several views.

Referring to the drawings, A in Fig. 1 is a screen-sash made in twoparts and hinged at B in such a manner as that itmaybe adjusted inwardlyand outwardly, as shown at Bin Fig. 3, the sides 0 being made in bellowsform of any suitable material, gum-cloth being preferred. The side D isformed of rigid material, such as wood metal, or prepared board. Besidesthe hinged adjustment shown at B, the said sash A and the side D are bybeing thus disposed in bellows form adapted to be adjusted toward andfrom each llther by means of the flexible connections 0 for the purposeof adjusting the size of the end opening E to any desired size orcapacity, which adjustment is controlled by means of the knuckle-jointedarm L, which is pivoted to the sash at F and to the side D at G andtogether at H and adapted to be rigidly locked to the sash A by means ofthumb-screws I.

An opening J is provided between the sash A and side D, and the sash Ais made longer than the side D and terminates in projecting lugs orextending ends K for purposes hereinafter fully explained.

Having described my invention, its opera tion is as follows: The sash Ais turned upon its hinges B to the position shown in Fig. 3 to allow thelugs K to be inserted within the window-sash ways of the car-window andthe sash A straightened upon its hinges by being drawn inward, when ittakes the position shown in Fig. 4 and is locked therein by dropping thecar-window sash upon it and tight ening the thumb-screw I to make rigidthe knuckle-joint. The opening E, as before explained, is also adjustedby means of the said knuckle-joint and thumb-screw. In a car with thismechanism attached within a windowhaving the end E disposed toward thefront end of the car and its rear end open, as shown at J, beyond theouter line of the ex terior side of the car, the ventilation and coolingproceeds as follows: The knuckle-joint lock is adjusted to the extent ofopening outwardly the side D, thus regulating the size of the front endopening E, which size controls the quantity of air admitted to the sashA, which sash A is covered with a line screen of any suitable materialadapted to separate cinders and dust from the inflowing air, causing itto pass into the car in a cleansed condition, the said cinders and dustpassing to the rear of the mechanism and out into the open atmospherethrough the opening J. It is obvious that when the opening E is largestthe volume of air admitted to the car will be largest, provided the caris in motion, and that the inflowing volume of air will be augmentedwith the increasing speed of the car and reduced with the decreasingspeed of the car, and that the said opening F may be closed to theextent of cutting 06 the entire inflowing current of air through thissource, and that any desired means may be secured by this mechanism,according to the will of the operator.

A partial substitute for the knuckle-jointed arm L is found in the chainL when adapted to adj ustably connect the sash A and the side D, thoughnot as desirable as the said joint L.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is- V 1. The combination, in a car-window ventilator,the screen-sash A, formed in two parts and hinged together in the middleof the ventilator, the side D, andthe flexible material connecting thescreen-sash with the said side, for the purpose set forth. W 7

2. In a car-window ventilator, the screensash A, the lugs K, formed uponeach end of the sash, the hinges B, the side D, and the flexiblematerial 0, connecting the side with the screen-sash, combined withmeans, such as shown and described, for adjusting the said sash, for thepurpose set forth.

3. In a car-window ventilator, the screenended case comprising the sideD, hinged' screen-sash A, and the material connecting the said side andsash, and means, such as shown and described, for adjusting and lookingthe sash to regulate the size of one of the open ends, substantially asset forth.

In testimony whereof I have affixed my signature in presence of twowitnesses.

ALEXANDER BLACK.
